Starting this autumn it is possible to test disinfection equipment for pathogen elimination in soilless cropping methods. It is also possible to test substances or products to eliminate pathogens from the nutrient solution and to clean the piping. The last group can also be tested for remnants which may be able to damage plants. According a strict protocol pathogenic bacteria, fungi or virus will ...

Wageningen UR Greenhouse Horticulture is involved in the establishment of horticultural research centers in the Middle East where food security and food safety are important political and social issues. The establishment of a horticultural center starts by formulating a research agenda for the coming years. Based on this agenda and other conditions, like budget, a design is made by Wageningen ...

This week at Horti Fair in The Netherlands, the horticulture industry's premier tradeshow, CleanGrow will introduce its breakthrough multi-ion measurement solution capable of analyzing up to six ions simultaneously. The product combines a carbon nanotube-based sensor with a multi-ion meter for on-site measurements and real-time feedback. Currently optimized for horticultural applications, the ...

In northern latitudes, producers of bedding plants depend on supplemental lighting during the late winter and early spring growing seasons. Unfortunately, these peak times for young plant production are also the darkest. Researchers have determined that a minimum amount of photosynthetic light (daily light integral; DLI) is necessary to produce high-quality young plants in greenhouses. In ...

Wireless sensor-based irrigation systems can offer significant benefits to greenhouse operators. Advances in sensor technology and increased understanding of plant physiology have made it possible for greenhouse growers to use water content sensors to accurately determine irrigation timing and application rates in soilless substrates. The wireless sensor systems provide more accurate measurements ...

Controlled-release fertilizers (CRFs) are a widely used method of delivering nutrients to nursery container crops. The fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water, and are then released into substrates over an extended period of time. Although the use of CRFs is an accepted practice, growers and researchers are always looking for ways to decrease ...
